How long does it take for a strawberry birthmark to go away?

My 2 yr. old has one on the side of her head next to her hairline, it has gone down from since she was a baby....it is still red and a little poofy. The doctors said not to worry about it will go away, but when?
How long does it take for a strawberry birthmark to go away?
My 3yr old has one on her back. The doc. said it would go down in a year or two. I don't see much difference at this point. However, I see some people say it can take longer. I have decided that as long as it is not growing and causing health problems.... I am leaving the decision for removal up to her when she is older.
Reply:Its gonna be there for a while, but it will gradually fade away over time it'll get smaller and smaller over the years
Reply:Some don't ever go away, but it will probably be hidden by her hair as she g rows.
Reply:sometimes they stay forever...they may get smaller but they dont always go away.
Reply:ive seen ppl that still have them as adults..but my son had one that was bright and raised up shortly after birth...now its barely there..hes 2 yrs old.
Reply:My daughter had a weird mark on her forehead, above her nose between her eyes, and it's still there (she is almost five now)...it almost looks like a permanent goose egg, as if she got socked in the face. My dad always points it out..."What happened to her head?" And I have to explain to him that it's always been there. Anyway...I thought strawberry birthmarks never go away. My kid's dad has one that covers almost the whole lower part of his right leg, from his foot up to his knee.
Reply:my brother was born with a stork bite or a strawberry on his fore head too, he is now 7, he still has it a little. It's getting fainter!
Reply:My little brother's didn't go away completely till he was 10 or 11, but it faded considerably for the few years before that.
